22 | /* Objdump overview. |
23 | |
24 | Objdump displays information about one or more object files, either on |
25 | their own, or inside libraries. It is commonly used as a disassembler, |
26 | but it can also display information about file headers, symbol tables, |
27 | relocations, debugging directives and more. |
28 | |
29 | The flow of execution is as follows: |
30 | |
31 | 1. Command line arguments are checked for control switches and the |
32 | information to be displayed is selected. |
33 | |
34 | 2. Any remaining arguments are assumed to be object files, and they are |
35 | processed in order by display_bfd(). If the file is an archive each |
36 | of its elements is processed in turn. |
37 | |
38 | 3. The file's target architecture and binary file format are determined |
39 | by bfd_check_format(). If they are recognised, then dump_bfd() is |
40 | called. |
41 | |
42 | 4. dump_bfd() in turn calls separate functions to display the requested |
43 | item(s) of information(s). For example disassemble_data() is called if |
44 | a disassembly has been requested. |
45 | |
46 | When disassembling the code loops through blocks of instructions bounded |
47 | by symbols, calling disassemble_bytes() on each block. The actual |
48 | disassembling is done by the libopcodes library, via a function pointer |
49 | supplied by the disassembler() function. */ |
